And pretty much unprovable - even with LISA - which in itself is still a hypothetical device.
Odd also, that the article claims that Gravity can only exist in 3D space. Given that several theories currently try to explain that gravity is so weak is that its actually a "leakage" of a hyper-dimensional force into our own 3D space - as we don't live in a 2D universe we cannot prove that gravity couldn't have an effect in 2D in a similar but different way to the effect it has on our 3D space.

Is this one of those "we don't f**king understand it" but it fixes the maths so YAY! Things?
Anyway I thought the 4thD was time?

So did I, but Einstein said Time only exists to stop everything happening at once!

i thought the 4thD was time too (or a games dev on the Archimedes
)
Einstein did call it spacetime though (if that's relevant)
